2023年5月1日 · Olfaction is the chemical sensation of gaseous odorants colloquially referred to as the ability to smell. The olfactory nerve (cranial nerve one) in coordination with other neuroanatomical structures in the nasal passages, neurotransmitters, and the cerebral cortex is responsible for carrying out this intricate chemosensory process.
Sense of smell - Wikipedia
The sense of smell, or olfaction, [nb 1] is the special sense through which smells (or odors) are perceived. [2] The sense of smell has many functions, including detecting desirable foods, hazards, and pheromones, and plays a role in taste.. In humans, it occurs when an odor binds to a receptor within the nasal cavity, transmitting a signal through the olfactory system. [3]
15.9H: Olfaction - The Sense of Smell - Biology LibreTexts
2022年5月15日 · Smell depends on sensory receptors that respond to airborne chemicals. In humans, these chemoreceptors are located in the olfactory epithelium — a patch of tissue about the size of a postage stamp located high in the nasal cavity.
Olfactory system - Wikipedia
The olfactory system, or sense of smell, is the sensory system used for olfaction (i.e., smelling). Olfaction is one of the special senses directly associated with specific organs. Most mammals and reptiles have a main olfactory system and an accessory olfactory system.
Sense of Smell: Structural, Functional, Mechanistic Advancements …
2022年9月19日 · Olfaction is the oldest sensory modality known in evolution. Odor detection is accomplished by an array of different ORs expressed by olfactory sensory neurons in the nasal olfactory epithelium. Olfaction signal transduction is crucial for sensing our environment.
Olfaction – Basic Human Physiology
Explain the process by which odorants activate olfactory receptors. Trace the path of olfaction from the olfactory receptors, to the initiation of an action potential in the olfactory nerves, through the olfactory bulb, the olfactory tract, and to the various parts of the brain.
Olfaction Definition & Meaning - Merriam-Webster
The meaning of OLFACTION is the sense of smell.
Olfaction - Basic Neurochemistry - NCBI Bookshelf
Olfactory neurons are the only mammalian neurons that are known to turn over throughout life. They are continuously replaced from the basal layer of stem cells. Two morphologically distinguishable types of dividing basal cell have been identified in mammals, the horizontal basal cell and the globose basal cell.
Olfaction - an overview | ScienceDirect Topics
Olfaction refers to the sense of smell, a unique sensory modality that plays a crucial role in mating, survival, and shaping the quality of life in humans. It involves the detection of chemical signals in our environment through a complex neuroanatomical structure and signaling cascades.
OLFACTION | English meaning - Cambridge Dictionary
Olfaction is distinct from the other sensory systems where peripheral sensory receptors have a relay in the diencephalon. To locate its host, the fish louse uses vision, olfaction, and …
